Answer:
X = 5
Step-by-step explanation:
1.- Write down your equation backwards so its easier to answer
2.- then subtract 7x and 3x
3.- write down the rest of your equation, 4x - 2 = 26
4.- subtract -2 on both sides now you have, 4x = 20
5.- Divide 4 on bothe sides
6.- and you should have the answer, X=5
The right answer is Option D.
Step-by-step explanation:
Boxes of ice cream received = 50
Ice-creams in each box = 12
Total ice-cream bars = No. of boxes * Ice cream bars in each box
Total ice-cream bars =

Answer: 278.30 pounds (if the gasoline does not contain ethanol)
317.12 pounds (if the gasoline does contain ethanol)
Step-by-step explanation:
If the truck averages 12 miles per gallon, then in 170 miles it consumes:
170mi/12mi = 14.17 gallons.
We know that for one gallon consumed, the carbon dioxide emitted into the atmosphere is 19.64 pounds. (assuming it does not contain ethanol)
Then for 14.17 gallons consumed, we have a emission of:
14.17*19.64 pounds = 278.30 pounds
I the gasoline contains ethanlol, for a gallon the emiision is around 22.38 pounds.
In this case the total emission is:
14.17*22.38 pounds = 317.12 pounds
Answer:
This is an isosceles right triangle, then we have
2 x u^2 = [6sqrt(2)]^2
<=> 2 x u^2 = 72
<=> u^2 = 36
<=> u = 6
